Bug Description

Binary package hint: grub2

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=10.04
DISTRIB_CODENAME=lucid
DISTRIB_DESCRIPTION="Ubuntu 10.04.1 LTS"

I installed my Lucid Lync inside a LVM-System with seperate (vg_1-boot) and configured the

 * /etc/default/grub

  - GRUB_DEFAULT=saved
  - GRUB_SAVEDEFAULT=true

With these configuration (either others) I cannot save the selected menu item to the file

 * (vg_1-boot)/grub/grubenv

Using a normal formated boot-partition it works as expacted.

Indeed, still true in current trunk:

static grub_err_t
grub_lvm_write (grub_disk_t disk __attribute ((unused)),
                 grub_disk_addr_t sector __attribute ((unused)),
                 grub_size_t size __attribute ((unused)),
                 const char *buf __attribute ((unused)))
{
  return GRUB_ERR_NOT_IMPLEMENTED_YET;
}

This method would need to be implemented (carefully!).

We won't be applying such a patch for the safety reasons given upstream. Some other method of handling save_env in such environments would have to be invented.
